SASH GUIDE.

Application i1ed `May 5, 1926. Serial No. 106,841.

The principal object of the invention is to provide a light, durable, inexpensive, and easily applied sash guide in which one of the sidewalls is'detachable to facilitate 1nsertion or removal of the associated sash.

^ Other important objects and advantages not herein specifically mentioned will be apparent upon a full understanding of the novel construction, arrangement and Operation of a guide embodying the invention.

For the purpose of exemplification, four different embodiments of the invention are presented in the accompanying drawing and following description. It will be understood,

however, that the invention is susceptible of embodiment in various other modified forms coming equally within the comprehensive scope of the claims.

5 The sash guide of the invention1 is essentially a channel member which has a removable side wall. It is adapted to be secured to a window jam 10 in sliding engagement with a window sash 11.

The guide illustrated in Figs. 1 to 4 inclusive consists of an angle strip 12 and a sash-retaining strip 13 which is detachably associated with the angle strip. The strip .12 is formed of sheet metal, and is characterized by a central web 14, two side flanges 15 and 16 which extend from the web 14 toward the jam 10, and two other side flanges 17 and 18 which extend from the flanges 15 and 16 respectively away from the fam, the flange 17 being contiguous with the ange 15 and terminating a substantial distance beyond the web 14, in order to form a guide 19 for one side of the sash stile, and the flangelS being spaced from the flange 16 and terminating about even with the web 14, in order to form a groove 20 between such flanges for the reception of the detachable sash-retaining strip 13.

The strip 13, like the strip 12, is formed of sheet metal, and, when positioned in the groove 2O of the strip 12, extends a substantial distance out of the groove beyond the web 14, in order to form a guide 21 for the other side of the sash stile.

The strip 13 is held in the groove 2O by means of a number of small screws 22 which pass through aligned apertures 23 in the flange 18 and the strip 13 and engage in threaded apertures 24 in the flange 16. The flange 18 may advantageously be s aced at its free edge a greater distance rom the flange 16 than the thickness of the strip 13 necessitates, in order that when the' flange 18 is drawn up as far as possible toward the flange 16 upon the strip 13, the flange 18 will react resiliently -against the heads of the screws 22 and prevent loosening of the same in service.

The strip 12, instead of being positioned directly against the jam 10, may be mounted on an interposed weather-proofing strip 25. The strip 25 may be formed of felt, rubber, or other resilient material suitable for the purpose. The strip 12 may be secured t0 the jam through the strip 25 by means of a number of screws 26, and the edges 27 and 28 of the .strip may be slightly embedded in the resilient material of the strip 25 by the clamping action of the screws 26, whereby to povide eflicient weather closures along those e ges.

The guide above described may be used in cooperation with a similar guid-e at-the opposite side of the sash, or with one which is dissimilar in that it has no removable side guides is removed, sufficient clearance is given to permit insertion or removal of the sash. A guide without a removable side wall is shown at the left in Fig. 1. It is characterized by a centrall web 29,. two flanges 30 of which extend from the web away from the jam 31, and two other flanges 32 which extend from the flanges 30 toward the\ jam in contiguous relation to such Hanges.

j A guide constructed in accordance with the invention is exceedingly light, durable and inexpensive, provides in cooperation with the felt lining strip an efficient Weather closure, may be readily applied, permits the attaching screws to Ibe located at close intervals throughout the length of the guides since both guides may be applied to the jams before insertion of the sashand makes it possible for the sash to be easily inserted or removed. Obviously either one or both of the side walls of the guide may be made detachable in accordance with the invention to permit the sash to be inserted or removed v from either or both sides of a window frame.

In Fig. 5 is shown a different embodiment of the invention in which the fixed vside wall of the guide is of double as distinguished from single thickness, being formed by a flange 33 which extends from the central web 34 away from the jam 35, and another flange 36 which extends from the Harige 33 towardthe jam in contiguous relation to such flange. In this guide, the removable sash-retaining strip 37 is arched throughout its length'at 38 to obtain a narrow spring contact between the sash and the strip 37 when such strip is drawn up resiliently against the sash at 39.

In Fig. 6 is shown a still different embodimentof the invention in which the y angle. strip consists of a central web 40, a

flange 41 which extends from one side of the web 40-away from the' jam 42, a flange 43 which extends from the other side of the web toward the jam, and another flange 44 which extends from the flange 43 away from the jam and terminates about even with the web 4Q. The flanges 43 and 44 are spaced apart in order to form therebetween a groove 45; for the reception of the sash-retaining strip 46, and the cooperating portions of the groove 45 and strip 46 may be so shaped as t0 permit the strip to be snapped int-o the groove and held resiliently therein without the use of screws. `A relatively thick weather proofing strip 47 may be positioned between the web 40 of the guide and the jam.

In Figs. to 11 inclusive is shown another embodiment of the invention in which the xed and removable side walls 48 and .49 of the guide are defiected toward each other along their outer margins, which shape provides narrow contacting areas between the guide and the associated sash. The removable sash-retaining strip 49, which is held in position in the groove 50 of the guide by means of a number of screws 51, is provided at thelocations of the screws with, o bayonet slots 52 for hooked engagement with the same. One of the screw apertures in the strip 49, however, is not in the form of a bayonet slot, but is o-f such shape as to hold the strip against movement in any direction ,T5

when the screw is Apositioned in the same.

This aperture,l 53, is preferably the lowermost one. As a result of the-bayonet slot arrangement above described, the sash-retaining strip 49 may be moved laterally into 80 the groove 50 in the guide with the open portions of the slots 52 in alignment with the screws 5l which are already in position in the guide, and the strip 49 may then be shifted downwardly a sufficient distance to cause the vertical portions of the slots 52 to interlock with the screws 51, in which position the aperture 53 will be brought into register with the corresponding screw aper- 'turesin the guide, and the bottom screw may 90 be thereupon inserted. As will be appreciated, it is only necessary to manipulate but a single screw in applying or removing the sash-retaining strip 49. The screws 51, other than the one which position-s the strip by engagement in the aperture 53 thereof, are so adjusted in the guide as to apply the desired amount of spring tension on the sash, and may be adjusted readily from time to time. Spring clips 54 may be secured to T00 the inside of the guide in such positions as to bear resiliently with a certain amount of .friction against'the Shanks of the screws 51, whereby to prevent the same from loosening in service. Therstrip 49 may be pro- 105 vided at a suitablepoint with an inconspicuous slot 55 into which the point of a screwdriver or other tool may be inserted in shifting the strip vertically in the groove in the guide to lock or unlock the bayonet joints. 11o
